Title: Improvements relating to high frequency inductors
IPC: H05B6/36
Filed: 1958-06-06
Abstract: 863,142. Annealing. OHIO CRANKSHAFT CO. June 6, 1958 [June 25, 1957]. No. 18179/58. Class 72 [Also in Group XI] An inductor particularly suitable for use in treating cranskshaft journals by high frequency heating is built up from end laminations 14, 15 separated by intermediate laminations 13, each of the latter having an inner ring 20 surrounded by an outer frame which provide auxiliary apertures. The assembly is held together by bolts 17 but rivets or welding may be used. The assembly thus provides hollow cavities 16 to which cooling and quenching liquid is supplied by pipes 19. The liquid passes out of nozzles 18 which are formed by recesses provided on one face of each of the intermediate laminations. Alternatively, passages may be provided through the ring 20, the ring 20 may be made of thinner material than that of the outer frame, or spacing frames may be provided between the frames of adjacent laminations. Each lamination is formed in two parts, one 23 being secured to a fixed support 24 and the other 22 being hinged to the support by a hinge 25. The current path includes a fixed conductor 31, two pairs of contacts 27, 29, and 28, 30, and the support 24. Insulation 26 prevents the inductor from being short circuited and the contacts 27, 29 make it unnecessary for current to pass through the hinge 25. Inserts for making the opening 12 smaller may be provided, Fig. 3 (not shown) and, by choosing the appropriate number of laminations, an inductor of any desired axial length may be built up.

Abstract: 634,863. Electrically heated cooking appliance. SUNBEAM CORPORATION. July 10, 1947, No. 18314. Convention date, Dec. 9, 1940. [Class 39 (iii)] [Also in Groups VI, XXXV and XXXVII] A thermostatically controlled cooking appliance for making waffles between two electrically heated grids 8 and 11, has wall means 94 extending downwardly from the lower grid 8 in a manner surrounding the thermostatic switch 68 and shielding it from the heating elements 41 of the lower grid. The components of the switch are secured to the said walls in a plane normal to the lower grid and a rod 97 threaded through one of the walls permits the setting of the switch to be adjusted. The grids are heated by helically coiled resistance wires 63 wound between insulating buttons 64, the buttons being received on pins struck from reflector plates 29 and 59 behind each grid. The upper and lower heating elements are connected in series and the circuit includes a lamp 53 to indicate when the heating coils are energized. The plates are so mounted that in their closed position relative vertical movement between the grids is possible.

Patent GB-184100-A (GB)
Abstract: 184,100. Pollak, J. E., (Siemens & Halske Akt.-Ges.). Oct. 19, 1921. Automatic exchange systems. - A private branch exchange having more lines than can be accommodated in a single level of the main exchange connectors is wired to the top two levels of these switches and is called by transmitting ten impulses each for the tens and units digits. The final impulse of the tens digit is rendered ineffective if there is an idle line in the ninth level, and similarly as soon as an idle line is reached in the selected level the remaining units impulses are rendered ineffective. The cut-off relays T<IX>, Tx of P.B.X. lines in the ninth and tenth levels are connected. to battery, while the cut-off relay T<VIII> of ordinary lines in other levels. are connected to grounds. During the vertical movement of the connector LW a relay P<1> is connected to an auxiliary wiper 100, the contacts of which in the ninth and tenth levels are grounded through back contacts of the line cutoff relays, so that as soon as a level is reached including an idle P.B.X. line, the relay P<1> is energized and opens the circuit of the vertical magnet H. At the termination of the tens impulses the relapse of the series relay V<2> energizes a selflocking relay U which prepares the circuit of the rotary magnet D. During the passage of the units impulses the series relay V<2> is again energized and connects the test wiper C through a circuit 24, 25, 27, P<2>, 27, 44 to the grounded wiper 100. The relay P<2> accordingly becomes energized in series with a cut-off relay T<IX> or T<X> as soon as an idle P.B.X. line is reached. The relay P<2> disconnects the rotary magnet D and short-circuits part of its own winding to mark the seized line busy. When connection is being made to an individual line in one of the first eight levels, the busy test is performed by the relay P<1>, the relay P<2> being on open circuit since the wiper 100 is on a dead terminal.

Title: Special effects generators for providing iris-type television displays
IPC: H04N5/265
Filed: 1972-04-21
Abstract: 1378310 Television RCA CORPORATION 21 April 1972 [22 April 1971] 18573/72 Heading H4F A special effects generator for providing an iris-type television display (video A displayed in a circle within video B display) is modified to allow for small diameter (less than 20% of the line length) displays. The generator includes an electronic switch 40 switched between videos A and B by pulses from a comparator 41. A composite parabolic waveform, having a horizontal rate parabolic waveform superimposed on a vertical rate parabolic waveform is fed via a variable gain amplifier 42 to comparator 41, which operates switch 40 to pass video A if this, signal is above a preset level and to pass video B if the signal is below the preset level. The comparator output is also fed to an integrator 44 and when there is to be a small diameter display (adjusted by adjusting the preset comparator level or the amplitude of the parabolic waveforms), the integrator 44 provides a reduced output which increases the gain of amplifier 42 to allow more decisive discrimination by comparator 41, and so a more error-free circle in the iris-display.
